In a disk drive suspension including a baseplate and a load beam, a boss portion and protrusions are formed on the baseplate. The protrusions are formed in positions on a first surface of the baseplate off a reference mounting surface in contact with a suspension bearing surface of an actuator arm. Further, the protrusions are formed on a second surface located opposite from the first surface and project relative to the thickness of the baseplate. These protrusions serve to prevent a plurality of baseplates from closely contacting one another during their manufacture.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A disk drive suspension comprising: a baseplate fixed to a suspension bearing surface of an actuator arm of a disk drive; and a load beam mounted on the baseplate, wherein the baseplate comprises a first surface including a reference mounting surface in contact with the suspension bearing surface of the actuator arm, a second surface located opposite from the first surface, a boss portion configured to be inserted into a mounting hole formed in the actuator arm, and a protrusion formed so as to project outwardly relative to a thickness of the baseplate from at least one of the second surface and a part of the first surface off the reference mounting surface.
2. A disk drive suspension of claim 1 , wherein a hole into which the protrusion is inserted is formed in a region of the load beam which overlaps the baseplate.
3. A disk drive suspension of claim 1 , wherein the protrusion is shaped so as to project in a circular arc from the first or second surface along a profile relative to the thickness of the baseplate.
4. A disk drive suspension of claim 1 , wherein the boss portion is allocated on the first surface, and the protrusion is allocated on the second surface.
5. A disk drive suspension of claim 1 , wherein a hole into which the protrusion is inserted and which avoids interfering with the protrusion is formed in the load beam.
6. A disk drive suspension of claim 4 , wherein a hole into which the protrusion is inserted and which avoids interfering with the protrusion is formed in the load beam.
